Abstract: The invention relates to a method and to a corresponding system for providing a dental prosthesis made from ceramic material having a colour matched to the patient comprising the following steps: (i) receiving a desired nominal colour for the dental prosthesis, determining a deviation between the nominal colour and actual colour of the sintered ceramic material by the control unit and defining a temperature time cycle having a cycle time suitable for compensation of the deviation, for sintering at a defined sintering temperature and creating a corresponding sintering program by the control unit; and (ii) adjusting the actual colour of the selected ceramic material to the nominal colour in the sintering furnace by the sintering program executed by the sintering furnace.
